The first series of Death Valley reaches its conclusion on BBC One this Sunday, June 29, at 8:45 PM. The finale, titled Death Valley, throws Detective Sergeant Janie Mallowan and consulting investigator John Chapel into a case that pulls at old wounds while forcing a difficult new reality.

After John’s consultant role is made official, Janie and John are compelled to seek a new equilibrium in their relationship. That fresh start is immediately tested when they begin looking into the murder of Janie’s mechanic, Dean Ward, a killing that occurred during a school reunion. The case quickly ties into a cold case uncovered by DC Chaudhry, leading Janie to reexamine her best friend’s suicide from 15 years prior.

Timothy Spall and Gwyneth Keyworth, as John and Janie, continue to anchor the show with their complicated partnership. Their differing approaches to solving crime lead to friction, but also a growing understanding of the friendship at the core of their working method. As they deal with the present murder, John’s unlooked for news puts their reconciliation to the test.
